I work for central IS, so this is the first stage of a consolidated service offering that we anticipate may encompass all of our staff and faculty. We bought what we could with what we had, anticipating that usage will grow over time as individual units migrate off their existing infrastructure.
1/3 of the available capacity is passive 3rd-site disaster-recovery. The remaining 2 sites each host both an active and a passive copy of each mail store; we design to be able to sustain a site outage without loss of service. Each site has extra space for several years of growth, database restores, and archival / records retention reserves.
Oh, and you probably don't even want to think about what we did for our Dovecot infrastructure. Clustered NFS servers with seamless failover, snapshotting, and real-time block-level replication aren't cheap. The students and faculty/staff not supported by an existing Exchange environment aren't getting any less support, I'll say that much.
Folks trust us with their education, their livelihoods, and their personal lives. I'd like to think that 'my fellow taxpayers' understand the importance of what we do and appreciate the measures we take to ensure the integrity and availability of their data.
